Cat Flap Fever Expands Custom Cat Door Business, Offering Superior Pet Access Solutions

Cat Flap Fever, a U.S.-based manufacturer of premium custom cat doors, continues to grow, providing high-quality, handcrafted pet access solutions. Founded by Christine McCarthy in Roswell, Georgia, the company prioritizes durability, functionality, and pet safety, offering a superior alternative to mass-produced cat doors.

Roswell, GA, March 22, 2025 — Innovative Pet Access Solutions for Cat Owners

Cat Flap Fever has established itself as a leader in the pet product industry by offering custom-built cat doors designed for durability, energy efficiency, and ease of use. Unlike standard expandable models that allow drafts and pests inside, Cat Flap Fever’s handcrafted doors feature high-quality materials sourced exclusively from North America.

Founder Christine McCarthy’s inspiration for the company came from her lifelong passion for animal welfare. After rescuing a stray cat struggling to adapt to an indoor environment, she developed a prototype cat door window insert to provide a seamless transition between outdoor exploration and indoor comfort.

“My first custom door changed the life of my rescued cat, Nikki, and inspired me to create solutions for other pet owners facing the same challenge,” said McCarthy. “Today, our products are designed to offer both safety and freedom for cats while maintaining home security and insulation.”

Handcrafted in the USA with Premium Materials

Each Cat Flap Fever door is made in Roswell, GA, with an emphasis on superior craftsmanship. The company sources durable flaps from a small U.S. business, ensuring long-lasting performance. Unlike mass-produced alternatives, these doors are designed to provide a secure, draft-free fit, preventing unwanted air leaks and pest intrusion.

Customers praise the doors for their reliability and ease of installation, making them a preferred choice for pet owners seeking a high-quality alternative to traditional cat doors. The company has seen consistent growth, with strong sales through its website and online marketplaces such as Amazon and Etsy.

Customer Testimonials Highlight Quality and Functionality

Cat Flap Fever has earned a loyal customer base, with pet owners raving about the company’s commitment to quality and customer service.

Jan R. shared:
“Better than I dared hope for! I’m hesitant to order online. I like to ‘kick the tires” of a product before purchasing. Took a gamble ordering this window insert and WON the lottery. Quality exceeds my wildest expectations. Fit like a tight glove (measure well). My 6 month old cat had it figured out after being shown twice. The older cat took a while, the magnets are firm, and she is timid. My answer was to remove one stop for each direction. They both use it day and night. I’m at ease about them on the long days away from home. I highly recommend this product.”

Monica C. added:
“Customer is just right! I needed to order a custom size window insert because nothing else worked, especially during the winter. I’m so glad I found Cat Flap Fever! They made a perfectly fitting insert that withstands severe winter weather and it looks great. They were quick to respond to my questions and concerns.”

Founder’s Journey: From Corporate Executive to Entrepreneur

Christine McCarthy’s transition from a Senior Vice President of Claims/Litigation to the founder of Cat Flap Fever was fueled by a lifelong passion for animal welfare. Inspired by early experiences assisting her late brother in rescuing and rehabilitating animals, McCarthy developed a deep empathy for stray and feral cats.

Her journey into business began when she took in a struggling outdoor cat named Nikki and created a prototype cat door to ease her transition into a home environment. This invention became the foundation for Cat Flap Fever.

McCarthy, who self-funds the business without external investors, has leveraged her corporate negotiation skills to establish relationships with vendors, overcoming initial challenges as a small business. “Not many vendors wanted to work with me on pricing when I was just starting out,” she said. “But persistence and a commitment to quality helped me build a growing, successful business.”

Cat Flap Fever now generates approximately $650,000 in annual sales and continues to expand its reach.

A Mission-Driven, Women-Owned Business

Beyond its commitment to high-quality products, Cat Flap Fever actively supports animal welfare initiatives. McCarthy, a long-time advocate for feline rescue, has participated in trap-neuter-return (TNR) programs and regularly donates to animal shelters and rescue organizations.

“Helping animals has been part of my life since childhood, and I’m proud that my business reflects those values,” McCarthy said. “As a woman-owned company, we prioritize quality, customer service, and a commitment to making a difference in the lives of pets and their owners.”

Award Recognition: Best Cat Door Window Insert in Georgia

In addition to its growing popularity and customer satisfaction, Cat Flap Fever has recently been recognized with an esteemed industry award. The company’s custom cat door window insert was named the Best Cat Door Window Insert in Georgia of 2025 by the prestigious Evergreen Awards. This recognition highlights the company’s continued commitment to innovation, quality craftsmanship, and dedication to enhancing pet access solutions for owners across the state.

“We are thrilled and humbled by this recognition,” said McCarthy. “Being named the best in our category is a testament to the hard work and passion our team puts into every product. We’re committed to continuing to provide the best for our customers and their pets.”

Expanding Reach and Future Growth

As Cat Flap Fever continues to grow, McCarthy remains dedicated to enhancing pet access solutions while supporting responsible pet ownership. With increasing demand for high-quality pet products, the company is well-positioned for future success, offering customers reliable, handcrafted alternatives to mass-produced cat doors.
